This Part 1 of an article intended for people who have not explored
the value of radio communications because they are not sure why or how
they should. Maybe some old amateur radio equipment languishes, dusty
and ignored, in a corner of the attic.
My husband and I utilize walkie-talkies as well as local, regional,
and national radio communications every week at our remote home in
Alaska. We have gained friends, allies, mentors, equipment, lessons
about weather spotting, check-ups after earthquakes and wildfires,
resources and emergency contacts through local, regional, and national
emergency response organizations. Our ham radio experience has
absolutely enhanced our confidence of continuing self-reliance in a
grid-down situation, and informed us about the local and regional plans
for emergencies – of whatever cause or form. Because of our location and the quality of our equipment, we are able to provide communications for emergency search and rescue operations occurring far away.
In this article, we outline how and why we use various radios for
communication, their benefits, and how we gain and maintain our skills
with them.
Getting Started
Anyone can listen to ham radio, but to transmit, one has to earn one
of three levels of amateur radio licenses (from the FCC in the U.S.).
The easiest one, called Amateur Technician, is what I had earned. I
studied a free, online guide and then arranged to take an in-person,
one-hour test for about $15. My husband has passed two other, harder
exams, so his highest qualification is referred to as an Amateur Extra
rating. Once we pass these exams, we are issued a call sign by the FCC
that allows us to transmit on ham radio frequencies. I have given my
call sign to my children in another state far away. During an emergency
when cell phones do not work (perhaps an earthquake up here), they
could contact an amateur radio enthusiast who could reach us through
local frequencies that work.
Handy Talkies – local
When visiting friends in various cities, I have seen them text each
other by cell phone with various messages, like “please pick up eggs on
your way home”. We utilize our handheld radios in similarly benign
situations around our acreage, but also for more significant reasons.
Our pair of older, inexpensive Midland (LXT600PA) handheld radios
stays plugged in by our kitchen table. They are powered by batteries but
recharged by solar, wind, or generator. With frequent transmissions,
they last about 8 hours without recharging. Occasionally, we leave them
in a pocket and forget to plug them back in. Unused, they last about
24 hours without recharging.
The rechargeable batteries last for about 3 years, so we bought
back-up batteries, which lasted another 3 years. After 6 years, the
transmit button (PTT) started sticking, so we bought a new set.
Because of a “one is none and two is one” philosophy, we have a second
pair of identical radios in our guest cabin, which get infrequent use.
Thus, we have been able to trade out one when another dies, (like when I
dropped one in the wood fired hot tub!)
As part of our daily routine, when either of us goes outside, we plop
a radio in a pocket. If I am in the cabin and my husband is in the
woods or doing chores outside somewhere, I might ping him about a
telephone call, or ask him, on his return, to bring something back from
the food shed, power shed, or greenhouse. We rarely go from one part of
the property to another without taking something “there” or bringing
something “here,” thus saving thousands of steps per day.
Another benign use of our handy talkies is for visitors in our guest
cabin, which is 500 feet from our main cabin. The most common use is
for them to let us know when they are awake and heading downhill for
breakfast and coffee! They may also alert us to elements of nature they
see, such as a marten chasing a hare, or a brown bear running after a
moose. One friend whispered a late-night sighting of the aurora borealis
– in case we were awake, too.
Twice, we even took the devices with us on cruise ships, to avoid
their charges for roaming mobile networks when we just wanted to find
each other. This worked very well, but when we left the devices in our
carry-on luggage at the airport, TSA confiscated them.
A more important use of these walkie-talkies at our rural home is for
safety alerts. We announce the sighting of a bear or moose and its
location, or tell the other that we hear a float plane descending or
snowmachines heading our way through the woods. Living in a very quiet,
remote location (only one other couple lives full-time within 10 miles
in any direction), such mechanical noises are very distinctive. In the
winter, when the deciduous leaves have fallen, we can hear motors about 4
miles away, depending on wind direction. We can tell when a
snowmachine is curving back and forth along a nearby frozen creek or
headed straight along a hard packed trail, or carving recreational
circles in powder-soft snow on a nearby frozen lake.
Very High Frequency – Regional Communications |
| EFJohnson mobile_5300-ES |
Our gear: Portable/Handheld, Kenwood (TH-D72).
Antenna: we
replaced the standard rubber ducky antenna with a Diamond Antenna
(SRH320A) that vastly increased the range and transmission quality.
Base station, Yaesu (FT-8900R, at our main cabin).
Antenna: This
radio uses a standard 2 meter magnetic mounted antenna that rises above
the metal roof of our cabin.
Whenever my husband travels to the road system by snowmachine, he
always carries his handheld Kenwood with him, often inside his jacket
to keep it warm. (His cell phone works in towns and some rural
locations where a cell signal can reach a repeater, but those are few
and far between in Alaska).
By radio, we can hear each other for about the first five miles of
the 3.5 hour trek from our home to the nearest road, but cannot hear
each other beyond that distance, largely because he descends into river
valleys. However, by testing every few miles along the route, we found a
high point where I can hear him clearly. It is about 2/3 of the
distance from our home, and 1/3 of the distance to the nearest put-in
point to a road (and a lodge where he warms up). So he always checks
in with me there.
We note his departure time from home or the lodge. Then, I keep the
Yaesu base station on during his travels, and note a half hour range
within which I anticipate he will call me from that good transmitting
location if his travels are uneventful. If I do not hear from him
within 2 more hours, I can contact locals to track him from the town
side or I can head out from this side on my snowmachine because I know
his departure time and route. Fortunately, we have never had to search
for him.
Another use of this device is available through the Internet site www.APRS.fi.
If you register your ham radio call sign and carry a radio with you, a
loved one can track your progress along a map display on the website.
We have done this both when my husband flies our Piper PA-20 float plane
and drives the snowmachine. More commonly, I imagine, people use this
service to monitor loved ones, for example, if a relative drives
cross-country or hikes into national parks where cell reception could be
limited.
Every day but Sunday, my husband participates in scheduled “nets” which are
times when a radio group knows to tune into a specific frequency to log
in and pass useful messages. We use our VHF (very high frequency) radio
to connect with members of local and regional amateur radio groups and
emergency responders including CERT.
High Frequency (HF) – Distant/International |
| Micom 3F |
Our rigs: ICOM 756ProIII and Micom2ES
Our HF (high frequency) transceivers enable national or long-distance
communications through organizations for which my husband volunteers
including the Civil Air Patrol, joint military service MARS, and DHS SHARES.
High-frequency radios require much larger or longer antennae in order to transmit long distance.
Our equipment:
- Two 90 foot folded di-pole antennas are oriented east-west. They can pick up stations several thousand miles away that are north and
south of the antenna.
- The third antenna is a long wire powered by a SG-230 antenna tuner
(NVIS) connected to a 167 foot long wire strung through the trees about
30 feet off the ground. It is used for communications to other ham
radio operators in-state.
- A large Log Periodic antenna is pointed Southeast, across the Lower
48 states. It is so sensitive that we can hear stations in Puerto Rico –
about 5,000 miles away, and Maine – about 3,300 miles away, when other
intermediate receivers cannot.
